It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-31959 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/anchore/quill (Go): affected all versions; fixed in 0.7.1\n- github.com/anchore/quill (Go): affected all versions; fixed in 0.7.1\n- github.com/anchore/quill (Go): affected all versions; fixed in 0.7.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-31959/ (Markdown: https://insights.sbomify.com/CVE-2026-31959/index.md)","id":"CVE-2026-31959","markdown":"https://insights.sbomify.com/CVE-2026-31959/index.md","name":"CVE-2026-31959","record":{"aliases":["GHSA-7q3q-5px6-4c5p","GO-2026-4671"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Go signing tool","requires_auth":"none","summary":"An attacker with TLS interception capabilities can force Quill to fetch arbitrary URLs, potentially exposing internal network data or cloud credentials.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"quill","vendor":"anchore"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Quill provides simple mac binary signing and notarization from any platform. Quill before version v0.7.1 contains a Server-Side Request Forgery (SSRF) vulnerability when attempting to fetch the Apple notarization submission logs. Exploitation requires the ability to modify API responses from Apple's notarization service, which is not possible under standard network conditions due to HTTPS with proper TLS certificate validation; however, environments with TLS-intercepting proxies (common in corporate networks), compromised certificate authorities, or other trust boundary violations are at risk. When retrieving submission logs, Quill fetches a URL provided in the API response without validating that the scheme is https or that the host does not point to a local or multicast IP address. An attacker who can tamper with the response can supply an arbitrary URL, causing the Quill client to issue HTTP or HTTPS requests to attacker-controlled or internal network destinations. This could lead to exfiltration of sensitive data such as cloud provider credentials or internal service responses. Both the Quill CLI and library are affected when used to retrieve notarization submission logs. This vulnerability is fixed in 0.7.1.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"SSRF in Quill via unvalidated URL from Apple notarization log retrieval","id":"CVE-2026-31959","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":3,"n_references":1,"next":{"headline":"DoS in Quill via unbounded read of HTTP response body during notarization","id":"CVE-2026-31960"},"packages":[{"ecosystem":"Go","fixed":["0.7.1"],"introduced":["0"],"last_affected":[],"package":"github.com/anchore/quill","purl":null,"source":"GHSA-7q3q-5px6-4c5p"},{"ecosystem":"Go","fixed":["0.7.1"],"introduced":["0"],"last_affected":[],"package":"github.com/anchore/quill","purl":"pkg:golang/github.com/anchore/quill","source":"GHSA-7q3q-5px6-4c5p"},{"ecosystem":"Go","fixed":["0.7.1"],"introduced":["0"],"last_affected":[],"package":"github.com/anchore/quill","purl":"pkg:golang/github.com/anchore/quill","source":"GO-2026-4671"}],"prev":{"headline":"Tornado has a DoS due to too many multipart parts","id":"CVE-2026-31958"},"products":["quill"],"published":"2026-03-11","related":[{"cvss_score":5.5,"headline":"Unbounded memory allocation in Quill via unvalidated size fields in Mach-O binary parsing","id":"CVE-2026-31961","kev_date_added":null,"published":"2026-03-11"},{"cvss_score":5.3,"headline":"DoS in Quill via unbounded read of HTTP response body during notarization","id":"CVE-2026-31960","kev_date_added":null,"published":"2026-03-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-12","vendors":["anchore"]},"summary":"An attacker with TLS interception capabilities can force Quill to fetch arbitrary URLs, potentially exposing internal network data or cloud credentials.","url":"https://insights.sbomify.com/CVE-2026-31959/"}
